Liliana asked her friend how many siblings they each have. Using the data plot, 1. which data value shows a peak?
2. which data is an outlier?
3. is the shape symmetric or not symmetric​

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
